AI Technical Summary
During the opening and closing process of the existing lift sliding door lock transmission for buildings, the door leaf is too heavy, causing the lifting state to feel slightly heavy, and the hand rebounds too quickly during landing, which poses a potential risk of injury.
A lifting sliding door lock transmission with self-adjustment function of opening and closing force is designed. By setting a parallel chute and a square solid plate support seat on the solid plate, combining the guide rod and the compression spring, the opening and closing force adjustment is achieved. The compression spring provides assistance when the door leaf changes from the locked state to the lifted state, sharing the opening and closing force of the handle; when the door leaf changes from the lifted state to the locked state, the compression spring provides resistance to suppress the rebound too fast.
It effectively reduces the opening and closing force during hand-held operation, prevents the door leaf from rebounding too quickly during landing, reduces safety risks during use, and improves the user experience.

Abstract
Description
1. Technical field
[0002] The invention relates to the technical field of building door and window actuators, and in particular to a lifting and sliding door lock actuator with an opening and closing force self-regulating function. (II) Background technology
[0004] After the hardware of the lifting and sliding door for buildings is installed, when the lifting and sliding door lock is turned by the handle, the door leaf is too heavy and it feels heavy in the lifting state, and the handle rebounds too quickly during the lowering process, posing a risk of injury. (III) Summary of the invention
[0006] In order to make up for the deficiencies of the prior art, the present invention provides a lifting and sliding door lock actuator with a self-adjusting opening and closing force function which has a simple structure, is safe to use, and is firmly fixed.
[0007] The present invention is achieved through the following technical solutions:
[0008] A lifting and sliding door lock with a self-adjusting opening and closing force function, comprising a slide plate that penetrates into a fixed plate, a mounting hole for a riveted lock point is provided on the slide plate, a square hole for fixing a lock body is provided on the fixed plate, and a transmission rod of the lock body is inserted into the hole of the slide plate, characterized in that: two parallel inclined grooves with vertical cross-sections are respectively arranged on both side edges of the fixed plate and are located above the lock body, a square fixed plate support seat corresponding to the position of the inclined groove is arranged on the side of the fixed plate, and two cylinders corresponding to the inclined grooves are respectively arranged on the adjacent two side surfaces of the fixed plate support seat; a guide rod is passed through the fixed plate support seat, a compression spring is passed through the guide rod, nuts and other fixings are fixed to the guide rod at the end of the compression spring and the lower end of the fixed plate support seat, a threaded hole is provided on the slide plate, the slide plate connecting seat is riveted to the threaded hole through a slide plate connecting rivet, and a fixing groove corresponding to the guide rod is provided on the slide plate connecting seat.
[0009] The present invention includes a linkage mechanism, an opening and closing force adjustment mechanism and an initial limit mechanism. During assembly, the force transmission component of the opening and closing force adjustment mechanism is fixed on the slide of the linkage mechanism, and then the force generating component of the compression spring of the opening and closing force adjustment mechanism is introduced into the fixed plate of the linkage mechanism. When the linkage mechanism is transferred from the lifting state to the locking state, the guide rod is inserted into the slide connection seat, and then the nut and other fixings connected to the fixed plate support seat are tightened. At this time, the locking point is in the locking position, and the initial limit mechanism is installed for limiting. When in use, after the door lock and other lifting and pushing hardware are installed in the specified position, the initial limit mechanism is removed. When locked to the lifting state, the door leaf is lifted, and the compression spring releases the compression amount to provide assistance, sharing the opening and closing force of the handle. When the lifting state is transferred to the locking state, the door leaf will fall rapidly due to its own weight, and the compression spring is compressed to provide resistance for the door leaf to fall, thereby effectively suppressing the problem of too fast rebound of the handle in cooperation with the door lock.
[0010] A better technical solution of the present invention is:
[0011] A positioning plate is placed in the long hole where the fixing plate and the locking point slide, and a threaded hole corresponding to the positioning plate is set on the slide plate, and the fixing screw passes through the positioning plate and is screwed into the threaded hole of the slide plate. The positioning plate is used as an initial limiting mechanism for limiting the position, and after limiting the position, the nut and other fixings at one end of the fixed support seat are unscrewed to avoid the situation where the door lock cannot be installed in the open state due to the release of the compression amount of the compression spring.
[0012] When leaving the factory, the lift and slide door lock actuator needs to be in the initial state (locked) for installation. When the handle is used to rotate the linkage mechanism lock body to put the door lock actuator in the initial state (locked), in order to prevent the door lock actuator from automatically rebounding, a positioning plate is placed in the sliding groove of the fixed plate where the locking point is located, and then the fixing screw is screwed in through the long hole of the fixed plate. The fixing screw is connected to the thread on the slide plate to achieve a firm fixation effect.
[0013] The lock body is provided with protruding ribs, the lock body and the fixing plate are fixed by squeezing, the transmission rod of the lock body is inserted into the hole of the slide plate, and a cylindrical pin is fixedly inserted into the concentric hole of the lock body and the fixing plate; preferably, the diameter of the cylindrical pin is 6mm; the lock body, slide plate, fixing plate and locking point form a linkage mechanism
[0014] The guide rod has two nuts and other fixings at one end of the compression spring, and one nut and other fixings at one end of the fixed plate support seat. When the effect of suppressing the rebound too fast and reducing the opening and closing force is not ideal, the compression amount of the dehumidification state spring can be changed by adjusting the relative positions of the nuts and other fixings at both ends.
[0015] The force transmitting component of the opening and closing force regulating mechanism of the slide connecting seat is connected to the slide by riveting; the fixed support seat, guide rod and compression spring are used as force generating components and are connected to the fixed plate by introduction.
[0016] The present invention has a simple structure, is easy to operate, and has a reasonable design. Through the deformation of the compression spring, it provides assistance when the door leaf is transferred from the initial state (locked) to the lifted state (opened), thereby reducing the opening and closing force during the handle operation. It provides resistance when the door leaf is transferred from the lifted state to the initial state, thereby effectively reducing the problem of too fast rebound during the handle operation. The present invention is suitable for wide promotion and application. (IV) Description of the drawings
